While readying the boat for the season this last week I somehow pulled the line used to tension the base of the main into the boom at the mast end. I'll swear that I used to have a knot on the line to prevent this but, it happened. Question is, how do I retrieve it. Both ends of the boom appear to have caps, these held by four screws. Do I just knock off the caps after removing the screws or is there anything else that I need to be aware of. I doubt if the caps have been off in thirty yeasr so removing them could be fun. Has anybody any better ideas than what I'm thinking. Jim G.
